3.0 Preventative Maintenance for SD-26400 Shaker System Components
3.1 SD-26400-550 Electro Dynamic Shaker System(s)
3.1.1 Only a qualified experienced Shaker System Technician should perform disassembly and assembly of the shaker system. During the warranty period it is recommended that a complete preventative maintenance be performed after 250 hours of operation, and each 1000 hours of operation thereafter or every six (6) months whichever comes first.
3.1.2 To ensure maximum efficiency, a preventive inspection schedule should be followed. The operational schedule of the shaker determines the inspection schedule. A shaker operating daily should be inspected more frequently than a shaker that is used less frequently. Tightness of electrical connections and screws should be checked on regular basis prior to operating the system.
3.1.3 The following parts should be inspected while the shaker is disassembled:
3.1.3.1 Electrical Wiring
3.1.3.2 Terminal Block
3.1.3.3 Air Bag for Load Support

3.2.1.4.2 Inspect for signs of overheating or melted insulation on three-phase power lines, main circuit breaker, power transformer, power supply section
3.2.1.4.3 Do not remove any grease-like compound found on high current joints
3.3 WCU1 Water Cooling Unit
3.3.1.1 Tests and Inspections (performed semi/annually):
3.3.1.1.1 Check the hose connections
3.3.1.1.2 Check the water level and purity
3.3.1.1.3 Replace the water output filter core regularly
3.3.1.1.4 Dirty water will clog the filter causing the Water Flow Interlock to trigger.
3.4 Model STGP-60-3 Platform Slip Table Assembly Slip Plate and Bearings
3.4.1 The slip table assembly consists of a steel moat structure, a magnesium slip plate, a precision ground granite, a precision ground base plate, seven (7) guide bearings and a low pressure (100 psi) oil pump. The steel moat structure acts as an oil reservoir. The granite slip surface is enclosed within this structure and is ground and lapped to a tool room grade (Grade B) finish to provide minimum friction during vibration testing.
3.4.1.1 Extra care must be taken to protect the top surface of the slip plate from dents and heavy scratches. Dents on the top surface of the slip plate usually create bulges on the bottom of the slip plate, resulting in improper load distribution on the granite surface and a non-uniform oil film between the slip plate and the granite. This could result in damage to the slip table system or the shaker
3.4.1.2 The slip plate is internally ported from the aft end of the plate. The ports are 3/8” diameter and extend through the slip plate approximately 1” past the center of the slip plate. All future machining of the insert installation should have the outer diameter of the installed insert at least ½” from the centerline of the ports.
3.4.1.3 Attachment bolts used on the top surface of the slip plate should not be long enough to contact the bottom of the inserted holes. This could result in damage to the critical bottom surface.
3.4.1.4 Open cell foam sheets are installed around the perimeter of the granite for additional oil filtering. The foam filter is also used to wipe off the bottom of the slip plate during vibration to minimize dripping of the oil around the perimeter.
3.4.1.5 The guide bearings have a maximum stroke of 3.25”. They consist of 1.50” diameter aluminum sleeves riding on chrome plated steel shafts. The guide bearings do not require direct oil lubrication. However, they do receive some oil lubrication from internal splashing and misting of the system during vibration.
3.4.1.6 The oil pump removes oil from the bottom of the reservoir and directs it into the magnesium slip plate where it is expelled onto the top surface of the granite. The underside of the magnesium slip plate is routed to disperse the oil over the entire granite. The oil then flows over the edge of the granite and returns, through the foam filter, to the oil reservoir. The oil flow rate is set at the factory and should not be readjusted except by a qualified technician. The proper oil flow is critical to the operation of the slip table system. The oil pump operates off of standard 110v electrical power.
3.4.1.7 The correct oil to be use is Shell Tellus 68 or equivalent.
3.4.1.8 Turn on the oil pump and wait at least 15 minutes before stroking the slip plate, and 30 minutes before running a vibration test.
3.4.1.9 Do not over torque the bolts – see manual for proper torque settings.
3.4.1.10 For best results distribute test article load over as much of the slip plate surface as possible.
3.4.1.11 The six (6) vibration isolators which sit beneath the steel isolated platform were inflated to detailed pressures (in manual) at installation. These pressures should be periodically checked and maintained. The isolators can isolate to 3 ½ Hz with air pressure. Without air pressure they can isolate to 5 Hz.
3.4.1.12 Periodically check the oil level in the slip table moat using a dipstick. The oil level should be at least 1 ¾” deep. If below this level or if air bubbles are seen in the oil return lines, add Shell Tellus 68 (or equivalent) oil’
4.0 SD Vertical Testing Assembly: The vertical guidance and load support system (referred to as “the vertical system”) was designed and manufactured specifically to provide simple linear guidance and load re-centering capabilities. There are two separate vertical guided head expander systems. One system contains a 60” X 60” head expander for mounting to a single shaker. The other system contains a 60” X 60” head expander for mounting to dual shakers. Both systems consist of the following components:
4.1 One (1) each, 60.0” magnesium head expander weldment.
4.2 One (1) each, steel upper frame weldment.
4.3 One (1) each, steel lower frame weldment.
4.4 Six (6) each, steel lower leg weldments.
4.5 Eight (8) each, steel angled braces.
4.6 Eight (8) each, Steel flexure pedestals.
4.7 Two (2) each, steel lockout brackets with hardware.
4.8 Eight (8) each, laminated flexure assemblies.
4.8.1 Regular maintenance to inspect the torque values of the bolts and visual inspections to verify the integrity of the wrappings is important.
4.9 Four (4) each, Firestone airbags and related hardware.
4.9.1 Do not exceed 90 psig in the air bags. The air bags should be inflated very slowly when additional mass is added to the head expander system. Adjust the regulators until the head expander is at mid stroke. Record the regulator pressure with the system unloaded. This will become the system’s “set pressure.” Always return the air bags to the “set pressure” before removing any test articles from the system. This will prevent sudden inflation of the air bags and uncontrolled movement of the system.
4.9.2 Prior to removing any mass from the system, deflate the air bags to the “set pressure”. If the magnesium fixture table is being removed from the system, the air bags must be set to zero psig and the lockout pins must be installed.
4.10 Two (2) each, Aluminum lockout/stroke limit blocks.
4.10.1 This system is equipped with a stroke limitation device. In the event that the shaker travels beyond its normal operating stroke, the stroke limitation device provides a hard mechanical stop. This device should be set to allow full stroke of the shaker armature but prevent over extension of the shaker armature and flexure guidance. This device should be checked prior to each operation of the system.
4.11 Two (2) each, special stroke limitation studs and hardware.
4.12 One (1) each, Air regulator and gauge assembly.
4.13 Four (4) each, hoist rings.
4.14 Two (2) each, shaker amplifier cut-off interlock switches.
4.15 One (1) lot, miscellaneous hardware.
5.0 Vertical Operation: When loading the system to perform normal operation in the vertical axis, the assemblies should be located at their mid-stroke positions. All stroke-limiting devices should be at their mid-stroke positions. Once the load is attached to the system, and the lockout bolts are removed, the system is free to move vertically. When the test is complete, the head expander system should be at the mid-stroke position. Set the airbags to their set pressure, remove the mass from the system, and install the lockout pins.
6.0 Removal of the Upper Assembly: This system is designed to allow the upper portion of the head expander system to be removed while leaving the support legs in place. To remove the Frame Assembly along with the head expander, make certain that the head expander system is at the mid-stroke position.
6.1 Install the two (2) lockout pins into the lockout receivers on the head expander. This is done by inserting the pins through the steel lockout brackets.
6.2 Remove the armature bolts from the head expander.
6.3 Relieve pressure from all airbags and disconnect the quick-disconnect fittings on the air-lines.
6.4 Support the system with an overhead hoist at the lifting ring locations.
6.5 Remove the bolts, nuts and washers that attach the Upper frame assembly to the Lower frame assembly.
6.6 Lift the Frame Assembly and set in a safe place. The Lower frame assembly and support legs should remain mounted to the floor/mass.
7.0 Installing The Upper Assembly
7.1 Verify shaker(s) are in the vertical position. Install 2 each, 24” long M10 threaded rods into the armature inserts (use the 500mm diameter bolt circle at 180 degrees apart). For installing the dual shaker assembly, install the 2 threaded rods on center of each armature.
7.2 Lower the Upper frame assembly onto the shaker armature(s), using the threaded rods for guidance. The Upper frame assembly should not depress the armature during this step.
